摘要：

Frequency-dependent, complex refractive indices for carvone in the mid-infrared from 750 to 5000 cm(-1) have been inverted from the Fourier transform extinction spectra of laboratory-generated aerosols recorded at room temperature. The refractive indices obtained in this analysis are in good qualitative agreement with the results of a previous thin-film study of carvone. However, a full quantitative assessment of this agreement cannot be made as tabulated data for the previous study are no longer available. The refractive indices, or optical constants, reported here add to the small number of frequency-dependent refractive index data sets for other organic compounds that are available in the literature. Such data can be used to elucidate the optical properties of a substance, which are of critical importance in the interpretation of remote sensing data and in the evaluation of how atmospheric particulate matter consisting of organic compounds may affect climate change.
